Welcome! This website is for the Psychophysics Application project at WINLAB. 

Our goal for this project is to create an iOS and Android application for a psychophysics study. This study involves users watching an hour long streamed video with varying packet loss and delay. For each pair of parameters for packet loss and delay, the app will prompt the user to rate the video quality on a scale of 1 to 4, with 1 being "Unacceptable" and 4 being "Excellent." A server controls the apps with a publish-subscribe messaging pattern by notifying the apps when to prompt the users to rate the quality of the video. After the user submits the rating, the apps will return that value to the server.
